Howdy - My experience building with EPP is quite limited, but I could not resist the PZL-P11c kit and ordered one from Marek today.
I watched several videos of Marek's planes flying and was impressed, his designs seem to be very airworthy. I look forward to trying my hand at one.
I may eventually have to try the Jer-2, that thing is just way too cool looking in the air.
Keep 'em flying, boys!
